My dog has a dead tick and bites. Should I worry or get blood tests?

Pet's info: Dog | Jack Russell Terrier | Male | neutered | 2 years old | 17 lbs

Good day I have a small dog and yester day I found a dead tick (if I recognized correctly) dead in his fur. He wears vectra 3D and seresto collar (it was on him only 3 days). I checked him and found bites in his ears, I presumed it was the insect. I strilized with alcohol and betatin. Shall I worry and take him for blood exams? Is it better to use effitix spot on instead vectra?

Depending on the amount of time the tick was on depends on what disease may have been transmitted. With flea and tick products though some repel and others kill in contact. Being as though you found the tick dead, the vectra seems to have worked. I would not panic necessarily at this time however monitor the bite(s) and make sure they are healing well. During an annual vet visit, to be safe, you can always ask to have something called a 3DX done or a 4DX done. These test are blood test that test for tick Bourne diseases as well as heartworms
